Hook to disable invoices with total 0.00

[J-B]

Hi, 

I have a hook (its not from me) that disable sending 0.00 invoices.

<?php
use Illuminate\Database\Capsule\Manager as Capsule;
function disable_00_invoices($vars) {
 
 $email_template_name = $vars['messagename']; # Email template name being sent
 $relid = $vars['relid']; # Related ID it's being sent for - client ID, invoice ID, etc...
 
 //Checking for certain template name, if so - this is our case
 if ($email_template_name == "Invoice Created" || $email_template_name == "Invoice Payment Confirmation")
 {
 //getting total of the invoice
 $data = Capsule::table('tblinvoices')->where('id',$relid)->first();
 //if it is equal to '0.00' we disable email sending
 if (isset($data->total) && $data->total == '0.00')

 $merge_fields['abortsend'] = true;
 }
 
 return $merge_fields;
}
 
add_hook("EmailPreSend",1,"disable_00_invoices");
?>

This hook works great, but it disable invoice that is paid via credit too.

I have try ...

if (isset($data->total) && $data->total == '0.00') && (isset($data->credit) && $data->credit == '0.00')

But this code isnt working. 

Anyone a idea how I can disable only 0.00 total invoices and not invoices that is paid via credit?

Your condition is wrong. This one should work.

if (isset($data->total) && $data->total == '0.00' && $data->credit != '0.00')

This code is not working too. Zero Invoices is sending again to the customers. 

 

Any other solution?

change your if statement to the following:

if ($data->total == '0.00' && $data->credit == '0.00')

so it will prevent invoices with total equal "0.00" from being sent, while allow invoices paid with credit to be sent normally
